Adding 2 cycle oil in the fuel ???

I've heard a number of older O/O doing this on older engines with no issues. Ive never done it myself. I cant see how it would hurt, just have to figure out a ratio oil to fuel.

 

From my book,...

Kerosene is sometimes used to keep diesel
from gelling and/or is used to circumvent paying fuel taxes. This is in fact true,
but it is very abrasive and causes excess wear. It actually isn't bad as a 'Roll your
own' anti-gel product if it is first mixed with a good ash-less 2-cycle engine oil
mixed at 128:1, to make it less abrasive. Some of the anti-gel products on the
truck stop shelves are nothing more than this anyways.

Also,...


Lastly, 'ash-less 2-cycle
engine oil' itself is actually a product that can slightly improve fuel economy as
well as reduce the abrasive effects of ULSD fuel. The proper mix ratio for a class-
8 truck is the problem. The proper mix ratio, after digging very hard to get the
scientific answer, and not some salesman's recommendation, is 200:1. At this
ratio, the combined benefit of both lowering component wear and the slight fuel
economy increase, is about 3% at best. Mixing it 128:1 or 148:1 will not improve
its effects, and for a truck that has two 100 gallon tanks, this is about 1 whole
gallon of 2 cycle oil per full fill up. Weighing costs, the 2 cycle oil would have to
be sold at less than $6 for a gallon just to break even, so, there again, yes it helps,
but no, it is not worth the cost of the product.

Rawze why do you think a book from Sri Lanka is free? I bet you just opened some malware. I ain't touching that link.

Sure the oil might be ashless but it has to get by the injectors first which are not designed to handle a thicker liquid. Hence not as good of a spray.

Try something like Power Service. It cleans the injectors and increases lubricity. If made up cures worked better someone would sell it as such. Just sayin'.

 

There was a time when owners would put old motor oil into the fuel tanks when they changed their oil. I have used transmission fluid to clean injectors.

 

I have heard that the bio diesel is the best lubricator against ulsd fuel.

 

The idea of using oil in the fuel system is valid, on older systems... not sure how much of that applies to, or effects on newer engines, fuel, or electronics?

The old timers had a good premise, since (good) motor oil has detergents that can't be found in #2 diesel. 2cycle engine oil was an after thought to the neoprine wax additive in motor oil. If they had thought longer and harder... they would have used fresh automatic transmission fluid which has a higher dose of detergent, and run their tanks lower before adding. <--- IDK the proper mix ratio? But slightly thicker was desirable.(and I do mean slightly!)

If it were me and my truck, new injectors not an option... I'd isolate the fuel system from the tanks and draw from smaller source with a proper mix of only injector cleaner/diesel. If you don't know of one harsh enough to cure problem, suggest SeaFoam, or GM Top engine cleaner.

These words from pre ECM days... IDK what it'd do today? Possible you'd clog exhaust filter and cost you just as much???

Best luck to ya!

 

Theres a product called stanadyne. Was recommended to me by a shop owner. Seemed like a good product. Nothing wrong with putting a quart of two cycle mix in the pre dpf stuff. Especially if the egrs been turned off.

 

it was once taught. that trans fluid makes a better cleaner then regular motor oil. the reason trans fluid isn't used in engines however, is it can't take the heat.

i use to add 1 gallon of trans fluid to a fill up. as much as i used it. about every 3 months. i could just take the money and have cummins do a complete power service. which includes overhead and injector flush. every 18 months.

every once in a blue moon. i'll put a quart in my car oil. at oil changes.

 

I was once told to put transmission fluid in the fuel filter any time I changed the filter, It burns very hot and cleans the injectors, I use to do it when I had a N-14 but haven't done it on my ISX For some reason,not sure why I haven't. What do ya think..............
